A jury began a fourth day of deliberations today in the trial of six men accused of murdering a Hell's Angel who was shot as he rode along a motorway.

The panel, which has so far deliberated for around 17 hours at Birmingham Crown Court, has heard seven weeks of evidence about the killing of Gerry Tobin on the M40 in August last year.

Simon Turner, a 41-year-old from Nuneaton, and 53-year-old Malcolm Bull, from Milton Keynes, are on trial alongside four men from Coventry - Karl Garside, 45, his brother Dane Garside, 42, Dean Taylor, 47, and 46-year-old Ian Cameron.

The exact addresses of the defendants, who all deny murder and possessing two shotguns, cannot be published for legal reasons.

Mr Tobin, a mechanic from Mottingham, south-east London, was returning from the Bulldog Bash bikers' festival in Stratford-upon-Avonwhen he was shot near Warwick services on August 12 2007.
